Calculate its perimeter and value of one interior angle. Solution: The polygon is an octagon, so we have, n = 8
Area of Polygon = ½ × n × Radius 2 × sin (2 × π /n) Area of Polygon = ¼ × n × Side 2 / tan ( π /n) A Table of Values And here is a table of Side, Apothem and Area compared to a Radius of "1", using the formulas we have worked out: Graph And here is a graph of the table above, but with number of sides ("n") from … See more A polygon is a planeshape (two-dimensional) with straight sides. Examples include triangles, quadrilaterals, pentagons, hexagons and so on. See more So what can we know about regular polygons? First of all, we can work out angles. All the Exterior Angles of a polygon add up to 360°, so: Each exterior angle must be 360°/n (where nis the number of sides) … See more We can learn a lot about regular polygons by breaking them into triangles like this: Notice that: 1. the "base" of the triangle is one side of the … See more Sounds quite musical if you repeat it a few times, but they are just the names of the "outer" and "inner" circles (and each radius) that can be drawn on a polygon like this: The "outside" circle is called a circumcircle, and it … See more WebInterior angle = 180 (n-2)/n, where n is the number of sides of the polygon. Explanation: Let us find the number of sides a regular polygon with an interior angle of 108°. ⇒ 180 (n−2)/n = 108° ⇒ 180n − 360 = 108n ⇒ 72n = 360 ⇒ n = 5 So, a regular polygon with an interior angle of 108° would have 5 sides.
WebA regular polygon has sides of equal length and equal interior angles. Examples of regular polygons are equilateral triangles, squares, rhombuses, and so on. A polygon will also have diagonals of the same length. Regular polygons are mostly convex by nature. On the other hand, concave regular polygons are sometimes star-shaped.
